Fitter​/Welder I

Welder / Fitter 1

Capitol Engineering is an established and expanding custom fabrication company delivering high quality engineered & fabricated steel products to a wide variety of industries including mining, agriculture, and general industrial applications. Capitol Engineering was established in 1937 and we are currently growing at a rapid pace and are looking to add a Quality Control Assistant to our team.

This position requires an experienced and detail-focused individual that wants to be part of a growing team. The ideal candidate will have a keen eye for detail, strong analytical skills, and a proactive approach to problem solving.

Capitol Engineering is hiring a Welder / Fitter 1 for our Phoenix fabrication shop. This is a hands-on production role that combines MIG (GMAW) and Flux-Core (FCAW) welding with material fit-up and assembly across the full range of custom products we build - structural steel, tanks, ducting, mining and wear equipment, and other specialty fabrications in carbon steel, stainless steel, aluminum, and abrasion-resistant (AR) plate.

We welcome candidates whose strength is welding, whose strength is fitting, or who do both. Whichever describes you, we want to hear from you - day-to-day assignments and skill placement are based on hands-on ability, and there is a clear path to grow into the other side of the trade over time.

Production Welding - MIG & Flux-Core

- Perform GMAW (MIG) and FCAW (Flux-Core) welding on assigned work pieces, in the positions for which you are qualified, in accordance with applicable Welding Procedure Specifications (WPS) and company quality standards.

- Weld on a variety of product types - structural components, tank sections, ducting, equipment frames, wear parts, and other custom fabrications - following work order instructions.

- Set up welding equipment and adjust parameters (wire feed speed, voltage, travel speed, shielding gas) per WPS requirements for each material and joint configuration.

- Perform tack welding to secure components in position prior to final welding sequences.

Fit-Up & Assembly

- Position and secure components for structural assemblies, tank sections, equipment frames, ducting, and other custom fabrications in accordance with work orders and shop sketches.

- Use measuring and layout tools - tape measure, combination square, torpedo level, framing square, soapstone - to verify component dimensions, squareness, and alignment before tacking.

- Prep weld joints using grinders, wire wheels, and flap discs, applying the correct tooling and contamination-prevention practices for the material being prepared.

- Report fit-up discrepancies or missing information to the Shop Lead before proceeding.

Weld Quality & Self-Inspection

- Verify joint cleanliness, fit-up condition, and WPS parameters before beginning each weld assignment.

- Perform visual self-inspection of completed welds against acceptance criteria - size, length, profile, fusion, porosity, undercut, and overlap - before releasing work.

- Report weld defects, non-conformances, or quality concerns to the Shop Lead immediately.

Equipment, Safety & Housekeeping

- Operate welding equipment, wire feeders, power sources, cutting tools, and associated tooling proficiently and safely; perform pre-use checks each shift and report issues promptly.

- Wear all required PPE at all times and follow facility safety protocols, lockout/tagout procedures, fume extraction requirements, and material-specific handling and ventilation practices.

- Maintain a clean, organized, and safe work station throughout the shift and report unsafe conditions or near-misses to supervision immediately.

- Perform other related duties as assigned in support of production operations.

What We're Looking For

Required

- High school diploma or equivalent.

- 3-5 years of production welding and/or fabrication experience across multiple product types.

- Strength in one or both sides of the role: an active welder performance qualification using GMAW (MIG) per applicable welding code or company WPS, and/or demonstrated fit-up and assembly ability using measuring and layout tools.

- Ability to read and follow work orders, shop sketches,…
